ELLWOOD IVINS, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE PATENTBUTTON COMPANY, OF WATERBURY, CONNECTICUT.

BUTTON-FASTENER.

SPECIFICATION forming part of Letters Patent No. 329,744, dated November3, 1885.

Application filed December 15, 1884. Serial No. 150,384. (No model.)

Be it known that I, ELLwooD IVINs, a citizen of the United States, and aresident of Philadelphia, Pennsylvania, have invented certainImprovements in Button-Fasteners, of which the following is aspecification.

The object of my invention is to provide a staple for firmly securingbuttons to garments, and this object I attain in the following manner,reference being had to the accompanying drawings, in which- Figure l isan exaggerated perspective View of my improved button-fastener; Fig. 2,a sectional view showing one way of using the fastener; Fig. 3, asectional view showing another plan of using it; Fig. 4, an invertedplan view of Fig. 3; and Figs. 5 and 6 views showing modifications.

The fastener is similar to that described in my Letters Patent No.309,785, dated December 23, 1884; and it consists of a. plate or ring,a, made of thin sheet-brass or other flexible but inelastic metal, andhaving four stems, b b, arranged to be passed through the four holes ofa button, each stem terminating in a spear-head, d, presenting twoabrupt shoulders, ff, or the head may have but two or three stems, andeach stem may have the termination shown in Fig. 5, so as to present oneabrupt shoulder, or it may terminate in a barbed point, as shown in Fig.6.

This fastener may be used in combination with a notched or recessedretaining ring or plate, as described in my before-mentioned patent, andas shown in Fig. 2, or said retaining ring or plate may be dispensedwith, and the fastener alone relied upon to secure the button, thespear-heads, after being passed through the fabric, being bent andstruck down at the back of the same. When the fastener is thus used, thespearheads are sunk into the fabric and the abrupt shoulders becomebarbs, which, by catching against the threads of the fabric, effectuallyresist efforts to detach the button.

The spear-headed prongs of my improved fastener must remain in thecondition to which they have been bent; hence the prongs, whileflexible, must be inelastic, and in this respect my improved fastenerdiffers from those in which the spear -headed prongs are elastic andhold a button by the engagement of the spear-heads with said button.

I claim as my invention A button-fastener in which are combined a head,a, and two or more downwardly-projecting prongs, b,Withabruptly-shouldered spearheads, the whole being made of flexible butinelastic sheet metal, as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ELLXVOOD IVINS.
